FOLDING COT AND THE LIKE.

Application filed Januan 24, 1922. Serial No. 531,346.

fl '0 all whom it may concern. V

Be it known that I, Josnrri GANNoN, a citizen of the United States,residing at Walton, in the county of Delaware and State of New York,have invented certain new and useful Improvements .in Folding Cots andthe like, of which the following is a specification.

This invention relates to folding cots and has for its object theprovision of means whereby the cot will accomn'iodateitself toirregular-ties and unevenness of the ground upon which it is set upwithout causing corresponding unevenness in the canvas top.

Other objects and advantages will hereinafter appear.

In the accompanying drawings:

Fig. 1 is a side view of a portion of a folding cot constructedaccording to my invention.

Fig. 2 is an end view of the cot shown in Fig. 1.

Fig. 3 is an end view of the cot in folded position.

Fig. 1 is a side view of the cot as shown in Fig. 3.

Fig. 5 is a perspective view showing the method of connecting the sidebraces to the legs of the cot.

Fig. 6 is an enlarged detail showing the sliding joint between thebraces of each pair.

Fig. 7 is a section through the joint shown in Fig. 6.

Referring to the drawings there is shown .a cot comprising transverselypositioned pairs of legs 10, 11, 12, the legs of each pair being pivotedas at 13 near their middle portion. The pairs of legs are suitablybraced by longitudinally positioned pairs of braces 15, 16, etc., thebraces of each pair being pivoted near their middle portions as at 17,18. The ends of the braces are connected 7 to the corresponding leg by apivotal connection permitting transverse, but not longitudinal, swingingof the braces, so that the latter may be folded against the pairs of thecot, the canvas may be attached to hooks 26 carried at the upperends ofthe;

legs.

Hitherto, if a. cot were set up on uneven ground, the braces wouldtransmit the unevenness from one pair of legs to all of the others, thuscausing the top of the cot, i. e., the canvas, to be low in'certainplaces and high in others. Thus assume that the lower ends 30 of legs 11were set up on a slight mound causing lower ends 30 to approach upperends 31. If pivots 17 and 18 were fixed, the pivots 32 and 33 and thepivots 34. and 35 would move toward each other, and if the lower ends oflegs 10 and 12 remained in contact with the ground the upper ends ofthese legs would be lower and the cot would be lower at these pointsthan. at legs 11, since only the lower ends of legs 11 have moved, theupper ends remaining practical- 1y stationary. To avoid this unevennessin the canvas at the top of the cot, the pivots 17 and 18 are not fixedbut are slidable. Each pivot comprises a collar 40, 4.1 (see Fig. 6),slidably engaging the outer face of each brace, and a. bolt 42 passingthrough both collars and both braces and operating in slots 43, 4 1 inthe braces.

It is apparent from the above description that should the lower ends 30(for example) stand on a slight mound so as to bring ends 30 nearer ends31, ends 32 and 33 and ends 3 1 and 35 need not move relatively to eachother at all, but that the variations in the positions of ends 30 and 31are taken up, in this case, by a movement of pivot 17 to the right andof pivot 18 to the left. Similarly any variations in the positions ofthe ends of any pair of legs will not be transmitted to the other pairsof legs but will be taken up by the movable pivots. The canvas can thusat all times maintain its horizontality regardless of the ordinaryvariations usually present on the surface of the ground.

The above description illustrates a preferred embodiment of myinvention, but it will be apparent that variations may be resorted towithin the scope of the annexed claims. 1

3 Claims:

1. In a folding cot bed, a plurality of pairs of transversely extendinglegs, a pair of braces pivotally connecting each set of adjacent pairsof legs at the ends thereof, each pair of braces having a slotintermediate the ends thereof, a U-shaped collar slidably engaging theouter face and adjacent edges of each of said bnaces and a boltextending through said slots and said collars for securing the collarsto the braces.

2. In a device of the kind described, a plurality of pairs oftransversely extending legs,

a pair of crossed braces pivotal-Ly comiectin-g each set of adjacentpairs of legs at the ends thereof, each pair of braces having guidingcollars for the same intermediate the ends thereof engaging the outerfaeeand adjacent edges of each of said braces, a pivot bolt for thebraces connecting the collars together, and a slot in each of saidibraces at thecrossing point in wh-iclrsaid bolt isvadazpted. to operate.

In testimonywhereof I affix my signature in presence of two witnesses.
